DISTRIBUTING BUCKET Application filed May 8,

My invention relates to new and useful improvements in distributing buckets for concrete pavers, and the present invention is an improvement on a somewhat similar type bucket shown in Patent No. 1,562,751 of November 24, 1925.

The present invention, like its predecessor, above mentioned, relates broadly to a distributing bucket having pivotal bottom doors, a trolley supporting the bucket in its to and fro movement on the boom, a cross shaft on the trolley, a tripping mechanism in the form of a segment mounted on the shaft, and means extending from the bucket doors to the shaft, so that a rocking of the shaft by this segment will cause the doors to open and close as desired.

In addition to the above, the present invention also consists in the formation and arrangement of parts, wherein both doors may be automatically opened and closed, or the mechanism may be so arranged that only one door will automatically open and again, the parts may be so arranged that only one door will automatically open, but a handle or handles may then be operated, if desired, to also open the other door.

An object, therefore, of thisinvention is to provide a bucket supported by a trolley adapted to move to and fro on the boom, the trolley having a cross shaft on which is mounted a segment, which is indirectly connected to the doors of the bucket, so that the doors may be automatically opened or closed as in the patent above mentioned, and to provide further means wherein only one door may be opened automatically or wherein only one door may be opened automatically and the remaining door opened by hand.

Still another object of the invention is to provide a bucket with swinging doors at its bottom wherein the doors may be opened and closed together either automatically or by hand, or one door opened and closed automatically, the other door being capable of being opened by hand, and in addition, to provide means wherein the opening movement of one door with respect to the other may be adjusted, so that the discharge opening between the two doors may be arranged Within certain :limits.

Still another object of the invention is to provide a distributing bucket for concrete pavers, wherein the several doors are nor- FOR CONCRETE PAVERS.

mally automatically operated, and wherein they may be operated by hand, if desired, and again wherein only one door may be operated automatically if a slower rate of discharge is desired.

\Vith these and other objects in view, the invention consists in certain new and novel arrangements and combination of parts as will behereinafter more fully described and pointed out in the claims.

Referring now to the drawings showing a preferred embodiment of my invention,

Fig. 1 is a side elevation of the bucket, the doors being shown in their closed ,position and a handle locked in position so that when the automatic door operating mechanism is operated, only one door willopen.

Fig. 2 is an end view of the bucket and the trolley for supporting the same, and a section of the boom shown supporting the trolley.

Fig. 8 is a side view showing a fragmentary portion of the bucket and one of the doors in its opened position. I

Fig. 4 is a similar view, but showing the door closed and the locking arrangement so positioned that when the automatic means for opening the doors is operated, both doors may swing to their open position.

Fig. 5 is a similar view, but showing the doors in their opened position.

Fig. 6 is a side view showing a fragmentary portion of the bucket, both doors being opened and the handle having been manually operated to open one of the doors.

Fig. 7 is a view on a reduced scale similar to Fig. 3, the adjustable means on the handle being moved so that one door is fully opened and the other door, only partly opened, and

Fig. 8 is a detailed section on line 88 of Fig. 6.

Referring now more in detail to Fig. 1, I have shown afragmentary portion of a boom 1 on which travels the trolly 2, which in turn supports a bucket 3 through the provision'o'f the hangers In this trolley 2 is across shaft 5 on which is mounted the segment 6, andthe stub arms 7, to which arms, in turn, are-connected the off-set arms 8, which appear at the opposite sides of the bucket and in turn support the yoke rods 9. the upper end of the yoke rods 9 to relieve any jars to the doors. The construction so far mentioned is all shown, described and Compensating springs 10 are shown at claimed in the patent to Charles E. Foote, No. 1,562,751 of November 24, 1925.

In the present application, a different form of means is shown extending between the yoke rods 9 and the doors 11 of the bucket, which arrangement will be shortly described in detail, but the means for operating the segment 6 by the cable 12, fragmentarily shown in the present application, is similar to the arrangement shown in the above mentioned patent, to wit, No. 1,562,751 and an earlier patent No. 1,443,454 of January 30, 1923, and another patent, No. 1,478,945 of December 25, 1923, so that a description of this part of the mechanism is not thought necessary. Suflice it to say, that an arresting of the cable 12 while the bucket is moving in either direction, will cause the segment to revolve to rock the shaft and either open or close the toggle and to open and close the doors of the bucket, depending upon the direction of travel of the bucket, and the position of the doors at the time the cable is arrested.

A handle 13 is shown mounted on the cross shaft 5 so that the toggle may be operated manually as well as automatically as in the former construction. In the present application, the bucket itself is slightly different from the bucket shown in the former patents in that the sloping forward and rearward ends are at such an angle that the doors 11 may be opened or closed without affecting the ground clearance.

On the opposite side of the bucket there are provided similar frames 14 for the support of the doors, these frames appearing at the lower portions of the sides.

Referring now to Figs. 2 to 6 inclusive, where the frames of the doors are shown on a larger scale than in Fig. 1, it will be 'een that secured to the two doors 11 at their ends, are the two hangers 15, each of which is pivotally mounted in the casting or frame 14, as at 16. As before mentioned, the doors on their opposite ends will be likewise supported and the lower surfaces of the doors may be provided with the downwardly extending flanges 17 and the angle bars 18, which are suitably bolted into place.

Projecting from the lower portion of the hangers and adjacent thereto, are the small lugs 19, to each of which is pivotally secured a link. The link to the left, 20, being also pivoted at its upper end within the yoke of rod 9, while the link 21 is provided with a slot 22 at its upper end, the pivot pin 23 passing within the slot and also pivotally retaining the aforementioned link 20. Also pivoted to the lug 19 (on the door to the right) and at the lower end of the link 21 is the long handle 24.

Although I have only described the sev eral links, hangers and handles on one side of the bucket, it is to be remembered that the arrangement is identical on the opposite side of the bucket.

In the handle 24, there is shown a cut out portion 25 in its lower edge, and fastened about this handle thereis shown a plate 26 with the large hole 27 near its lower end, while a plurality of small holes 28 are shown near its upper end, so that a bolt 29 may be passed through one of these openings 28 and a hole in the handle, so that the forward end 3-9 of the plate may be moved and set with respect to the edge 31 of the cut out portion in the handle. The purpose of this will be shortly described.

To understand the various ways in which the doors may be opened and closed, it c. n be best understood by first referr ng to 4. In this figure, the handle 24 is shown as pinned or locked in a substantially upright position by the pin 23 being passed through the opening 27 in the plate. In this Figure the doors are shown in their closed position and if the segment and toggle (Fig. 1) is operated, the yoke rods 9, of course, will be lowered and both doors will swing to their farthest open position as shown in Fig. as the handle 24, it will be remembered, is p nned in the yoke rod 9 and the slotted link 21 does not function except in conjunction with the handle. A. return of the segment and a. closing of the toggle (Fig. 1) will again pull the doors to their closed position.

As before mentioned the rocking of the segment may be done automatically or by the handle 13.

Of course, when the toggle is broken, the weight of the contents of the bucket will force the doors open, and in the arrangement just described, the bucket will be emptied quickly as the bottom doors are both allowed to swing to their full open position.

Referring now to Figs. 1 and 3, the han dle 24 in this instance shown as swung); or dropped downwardly and the out out portion 25 and the lower edge 30 of the plate abut a small pin 32 positioned at the pivotal point of the hanger for the left hand door.

If the toggle is broken one of the doors 11 to the left may swing to the position shown in Fig. 3 as the yoke rod 9 lowers but the handle 24 in this instance, which it will be remembered is secured to the lug on the door hanger at the right, being looked over the pin 32, the link 21 cannot move downwardly and the door to the right will be looked as above described, and the toggle broken, the bucket will now discharge at half the rate than it did in the former instance where both doors are allowed to swing to their open position.

Keeping in mind Fig. 3, and supposing it is desired for some reason when the bucket is discharging at half its rate, to open the other door, the handle 24 would be slightly raised; in fact, the operator would stand in back of the bucket and slightly raise both handles 24 and they would then be freed from the locking arrangement and would assume the position shown in Fig. 6, thus allowing the other door to swing open and the slotted link 21, of course, travelling on the pin 23. In other words, the length of the handle 24 from the pivotal point 19 to the locking pin 23 is now longer than the length of the slot-ted link 21.

A closing of the toggle will automatically close both doors as shown in Fig. 1.

As far as the description has proceeded, it will be seen that the arrangements of the doors and their parts are such that both doors may be opened or closed as desired, or only one door may be opened and further that if one door is opened and the other held closed, this may also be opened by a shifting of the handles.

There is one more arrangement which might be put into effect, and that is the amount of swing of the door to the rightmay also be regulated by a movement and setting of the plate 26 along the handle 24. In Fig. 7 I have shown the plate moved upwardly on the handle 24, thus in reality lengthening that part of the handle between the pivotal point 19 and the pin 32, and thus allowing the door to the right to assume a partly open position, so that one door is all the way open and the other door is partly open, and in this manner, the bucket may be made to discharge at a slightly faster rate than if one door only were open, and of course, less than if both doors were fully opened.

From the foregoing it will be seen that I have so constructed the bucket and its door and the operating mechanism for the doors, that the rate of discharge of the bucket may be varied to suit the different requirements. I The arrangement is one which has proved efficient in practice, is simple to operate and will withstand thehard usage incident to a device of this character.

Many slight changes might be made withmove to and fro on the boom, doors located at the bottom of the bucket, a toggle arrangement carried by said trolley and connected with the doors of the bucket, the doors arranged to swing towards and away from each other, means connected with one of said doors and adapted to be secured to a part of the toggle arrangement whereby both of the doors will swing to an open or closed position on an opening or a closing of the toggle.
